#### If 1+4=5, 2+5=12, and 3+6=21, what is 8+11? Viral math Puzzle answer

**Answer: **8+11=96

**Solution: **

**Correct Answer: 8+11=96 **

**Solution: 1**

If you look at first 3 Equations **a + b means a + ab**

a+b => a+ab

Let see now how it works for all equations ,

1 + 4 means 1 + 1(4) = **5**

2 + 5 means 2 + 2(5) = **12**

3 + 6 means 3 + 3(6) = **21**

now will apply same formula for the last equation **8+11=?**

8 + 11 means 8 + 8(11) = **96**

**So final answer is 96 is proved.**

**Solution : 2**

1 + 4 = **5**

**5 **+ 2 + 5 = **12**

**12** + 3 + 6 = **21**

**21** + 4 + 7 = **32**

**32** + 5 + 8 = **45**

**45** + 6 + 9 = **60**

**60** + 7 + 10 = **77**

**77 **+ 8 + 11 = **96**

Once again we get the answer of 96, that’s surprising!

**Alternate method : **

a+b= a+b(sum of the previous equation)

**1 + 4** = **5.**

**2 + 5** (plus the previous sum of 5) = **12.**

**3 + 9** (plus the previous sum of 12) = **21.**

same logic will apply for last equation also

**8 + 11** (plus the previous sum of 21) = **40.**
